Tungsten carbide is immensely hard and is very important to the metal-working, mining and petroleum industries. It is made by mixing tungsten powder and carbon powder and heating to 2200°C. It makes excellent cutting and drilling tools, including a new ‘painless’ dental drill which spins at ultra-high speeds.

If your wire needs to have the smallest diameter with the highest strength, Tungsten-Rhenium Wire is the wire to use. Another benefit of WRe wire is elevated specific resistance at the hot and vibration strength. Tungsten-Rhenium Wire has a density almost equal to Tungsten …

Aug 06, 2012· Rhenium is a silvery-white metal with one of the highest melting points of all elements, exceeded by only tungsten and carbon.It also has one of the highest boiling points of all elements. It is also one of the densest, exceeded only by platinum, iridium and osmium.Rhenium has a hexagonal close-packed crystal structure, with lattice parameters a = 276.1 pm and c = 445.6 pm. [15]

** Tungsten-Rhenium alloy thermocouples are supplied in standard 300 mm (12") lengths, which corresponds to each leg for a 600 mm (24") total length. Change suffix “-12” in model number to indicate additional length required in inches.

Tungsten (W) chemical structure, technical & safety data, discovery. Tungsten Properties. Tungsten is a Block D, Group 6, Period 6 element. The number of electrons in each of tungsten's shells is 2, 8, 18, 32, 12, 2 and its electron configuration is [Xe] 4f 14 5d 4 6s 2. The tungsten atom has a radius of 137.pm and its Van der Waals radius is 200.pm.

Rhenium was also recovered efficiently and selectively from rhenium–tungsten solutions (initial concentration 10.4 mM for each metal): when the pH ranged from 7.0 to 12.0 and the irradiation time was 6 h, the rhenium recovery was 90–95% and the rhenium recovery ratio was 7.3–45 times that of tungsten.

Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials.The atoms in the materials diffuse across the boundaries of the particles, fusing the particles ...

Tungsten, Nickel and Copper/Iron Alloy (HD17BB) Originally developed for boring bar applications, Mi-Tech Tungsten Metals’ HD17BB provides the benefits of both iron and copper. While still an excellent choice for tooling, it is also recognized as a cost-effective alternative to traditional tungsten…

Tungsten is one of the most promising materials for high temperature components in any future nuclear fusion tokamak. In this study tungsten-ion implantation has been used to simulate the damage caused by neutrons in pure tungsten and tungsten 5 wt% rhenium.This damaged layer is only 300 nm deep so conventional mechanical tests cannot be used to investigate it.

Tungsten rhenium alloy can be used over a wide temperature range (–196°C to 2,760°C) and standard temperature tables (ASTM E230 and E1751) are available from 0°C to 2315°C. Rhenium improves the properties of tungsten. Tungsten rhenium alloys are more ductile at low temperature while stability under high temperature is improved as while.

Rhenium is a silvery colored metal which resists corrosion and oxidation but slowly tarnishes in moist air. It is soluble in nitric and sulfuric acids. Applications for the metal include its use as an alloying element with tungsten, the resulting alloy having a very high electrical resistance making it suitable for …

Because of the inherent brittleness of unalloyed Tungsten, Rhenium has been added to the positive leg of types C and D to improve handling characteristics. The average emf of types C and D is slightly less than that of the unalloyed type G. Sold only as matched pairs. A double foot is a foot of positive and matched negative wire.

Rhenium improves the properties of tungsten. Tungsten-rhenium alloys are more ductile at low temperature, allowing them to be more easily machined. The high-temperature stability is also improved. The effect increases with the rhenium concentration, and therefore tungsten …
